About these units
Exagram (Eg)
An exagram, equal to 10¹⁵ kilograms, is used to describe masses of planets, moons, and extremely large terrestrial reservoirs (e.g., total mass of Earth's atmosphere ≈ 5 Eg). Because of its enormous scale, the exagram rarely appears outside astrophysics or large-scale geophysics. When used, however, it provides a powerful sense of magnitude—allowing scientists to describe Earth systems at the grandest scales with simple, comprehensible numbers.
Didrachma (Biblical Greek) (didrachma)
The didrachma, weighing around 8.5–9 grams, represented two drachmas. It appears in Greek, Roman, and biblical texts, often as a common temple tax or civic fee amount. Its moderate size made it practical for everyday transactions, bridging smaller denominations and larger, more valuable coins such as tetradrachms. The didrachma's consistent appearance in multiple cultures shows how interconnected the ancient Mediterranean economies were.
